General tips
Dark meat is more forgiving than breast because the higher fat and collagen content insulates the muscle fibers. That means you have a wider window before texture degrades. A thigh at 162°F for 6 h and a thigh at 162°F for 8 h taste nearly identical, which is not true of lean breast meat.
Always cook dark meat bone-in and skin-on when possible. The bone acts as a heat buffer that keeps the interior juicier, and the skin protects the surface from the water bath. You can remove the skin after cooking if you prefer, but cooking without it sacrifices moisture.
The single biggest improvement you can make to dark meat is drying the skin completely before crisping. After the bath, pat with paper towels, then let the pieces sit uncovered on a rack for 5 min. The drier the skin, the faster it crisps, and the less time under heat means the interior stays at your target doneness.
Bag juices from dark meat are liquid gold. Strain them, reduce by half with a splash of wine or vinegar, and mount with a knob of butter. You now have a pan sauce that took 30 sec of actual work and tastes like it took an hour.
Save rendered fat from the bags and the searing pan. Chicken schmaltz is one of the best cooking fats in existence. Strain into a jar, refrigerate, and use it for roasting potatoes, sauteing vegetables, or making the crispiest fried rice you have ever tasted.
Anti-tip: do not sous vide boneless, skinless thighs above 170°F expecting them to hold together for plating. At that temperature the connective tissue has fully dissolved and the meat shreds on contact. That is great for tacos and bowls but terrible if you wanted a whole thigh on the plate. Keep it at 160°–165°F for whole-piece service.
Sliceable tips
Pat the skin completely dry before broiling so it bubbles instead of steaming.
Use bone-in thighs for the juiciest results - the bones buffer heat and keep the interior tender.
Strain bag juices, reduce with white wine, and mount with butter for an instant pan sauce.
Confit tips
Store confit thighs submerged in their fat in the fridge for up to a week - warm gently to re-liquefy.
For tacos, crisp shredded meat in a dry skillet before saucing to keep texture lively.
If you want to serve whole, broil skin-side up until blistered and sprinkle with flaky salt.
Shredded tips
Shred while still hot - once it cools, the fat re-solidifies and shredding gets stringy.
Broil shredded meat in a single layer to get crispy bits before saucing.
Freeze flat in resealable bags with juices so you can break off portions for quick meals.
